CHARLES L. COF FIN, OF DETROIT, MICHIGAN, ASSIGNOR TO ELECTRIC METAL WORKING COMPANY, OF DETROIT, MICHIGAN, A CORPORA- TION METALLIC VESSEL.

Specification of Letters Patent.

- ratented April 3,1906.

To all whom it may concern:

Be it known that I, CrLARLEs L. CoFFrN, a

' citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Metallic Vessels, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates particularly to metallic vessels of the type wherein the body is surrounded by an airspace or chamber formin insulating means for protecting the vesseIcontents and it consists in the novel construction of a receptacle or vessel of this character, in the eculiar manner of insulating the same, and in other details of construction, as will be more fully hereinafter set forth.

For'the purpose of illustrating my invention I have shown the vessel in the form of a metallic keg or barrel, of which Figures 1 and 2, respectively, are views in elevation of the outer and inner shells composing the vessel-body. Fi 3 is a perspective view of one of the heac s for the barrel. Fig. 4 is a vertical central section through the barrel; and Figs. 5 to 8, respectively, are modifications.

The body of the barrel is composed of two metallic shells A and B, preferably concentrically arranged and spaced one from the other toform an air space or chamber C for insulating purposes. The outer section is preferably of greater length than the inner, and two are united by means of the barrelheads D, as hereinafter set forth.

Each head is preferably concaved and formed with two vertical spaced flanges a and b, one above the other, and an intermediate lateral portion or section 0, which unites the flanges. The heads, as shown in Fig. 4, are fitted within the ends of the inner section with their vertical flanges a engaging the end portions of the shell. The transverse portions or ofl'sets c ofthe head extend across the space between the shell-sections, acting to space the latter in the manner desired to form the insulation, while the vertical flanges b engage-the outer end portions of the outer shell, as plainly shown. As a matter of reference a chime-hoop E is fitted over eac end of the barrel and extends over into the head, preferably into proximity to the lateral offset portion 0. In the. side of the barrel a bung of any suitable type, as F, may be placed, the bung preferably used being in the form of a threaded a ertured flange (indicated by the referenceotter F) riveted to the inner section and engaging an opening formed for the same in the outer shell.

From the description thus set forth it will be obvious that the inner shell is suspended from the heads of the barrel, which is an exceedingly desirable construction, in that the inner section is protected against any jars or blows that the barrel may receive.

In case it is desired to insulate the heads of the barrel as well as the body the additional insulation may be obtained by employing an auxiliary head, using the latter either as an outer head, as indicated in Fig. 5, or as a head for the inner shell, as shown in Fi 6. Where an insulated head for the barrel is used, a bung-flan e, as G, is employed, similar to the one alrea y described.

In Fig. 5 the auxiliary head H is flanged, as at I, and is fitted within the vertical flange b of the head D at a distance above the latter to form the desired air space or chamber J.

In Fig. 6 the barrel is shown as formed of a headed inner section or shell, the heads K therefor being flanged and welded within the shell ends, as shown, the outer section A having its head-formed in the same manner as previously described.

In the several constructions of the barrel heretofore described the heads for the barrel have been formed in each instance with vertical flanges and a transverse portion connecting the same. If desired, the barrel or keg may be made up with heads differing from this construction in that the outer vertical flange is entirely dispensed with, as shown in Figs. 7 and 8. Here the inner shell has the inner vertical flange and the laterallyprojecting spacinghportions, while the outer shell is driven tig tl over the spacing-section and the parts he d together by frictional engagement. This construction of barrel is useful for many purposes, but is not espe- 01' ally adapted for use where it would be subjected to rough handling. It may be easily reinforced, however, and inde endent longitudinal movement of the she -sections prevented by the use of chime-hoops L, as .shown in Fig. 8, the hoops extending over the outer section and preferably into engagement with the spacing-section of the head, or by other means which would readily suggest themselves to one skilled in the art.

What I claim as my invention is 1'. A metallic barrel comprising an outer metallic headed shell, and an inner shell in sertible within and suspended from the heads of the outer, free from the walls thereof.

2. In a metallic barrel, the body formed of two spaced shell-sections arranged one Within the other, and a head for the body carrying a flange connectin with the inner section and a spacing an closure member extending between the sections.

3. A. metallic barrel, consisting of a body formed of two concentrically-arranged spaced shell-sections, and heads for the body carrying integral therewith outwardly-projecting annular flanges forming means of connection between the heads and the inner section, and

lateral spacing-flanges extending intermediate of and closing the space between the shells.

4. A. metallic vessel consisting of a body comprising two separated shell-sections arranged one within the other, and heads having integral spacing portions for and uniting slates the shells, in. different planes from the planes of the heads.

5. A. metallic vessel consistin of a body composed of two separated. she ls arranged one within the other, heads for said body, separated vertical flanges upon each head engaging the ends of the shell-sections, and lateral portions upon the heads uniting the flanges and covering the space between the shells.

6. A. metallic vessel comprising a headed inner shell-section, an outer shell-section spaced. from the inner, and heads for the outer shell uniting the sections.

7. A; metallic vessel comprising a headed inner shell-section, an outer shell-section spaced from and extending be 0nd the ends of the inner, and heads for t e outer shell. uniting the sections.

In testimony whereof I aflix my signature in presence of two witnesses.
